We will use resource Id in this tutorial for the playback of

audio(.mp3) file. After reading this topic you will be able to

make a basic audio player.

Android has MediaPlayer class which holds the functionality

that we need to build a music player. In this tutorial we will

cover basic methods with their explanations so that user can

enhance functionality as per need. In this tutorial we will use

raw folder to hold the audio file having extension .mp3 for

the playback of specified file.

Objective :

To provide familiarity about the playback of media files.

Implementation of MediaPlayer class for playback.To provide functionality of seekbar to control position of

playback.

Classes used to perform this task:

MediaPlayer class.

Handler class.

Runnable class

Introduction to classes:

MediaPlayer Class : In android MediaPlayer class is very

powerful which contains wide range of functionality like audio

playback, video playback etc. MediaPlayer class contains the

following main methods :

static MediaPlayer create(Context ctx, int resourceId) :

This method is used to set the path of audio file with in

context and resourceId will

give the id with in asset folder.

boolean isPlaying() : This method will tell that

MediaPlayer is playing or not.

Int getDuration() : This method will return the total

duration of current file.

Int getCurrentPosition() : This method will return the

current postion of playback.

void start() : This method will start the playback ofMediaPlayer.

void pause() : This method will pause the playback of

audio file.

void stop() : This method will stop the playback of audio

file.


4/22



void reset() : This method will reset the MediaPlayer to

uninitialized state.

void seekTo(int millisec) : This method will seek the

playback to specified seek time in millisec argument.

void setLooping(boolean value) : This method will set the

repetition of MediaPlayer as per value given, either true

or false.

Handler Class : Handler class is used to handle the threads. We

have used postDelayed() method to produce delay of 1 second.

Here is below the method syntax:

public final boolean postDelayed(Runnable object, long

delayMilli) : This method is used to introduce the delay in

execution of thread which is object of Runnable and

delayMilli is the delay time in milliseconds.

Runnable Class : Runnable class is used to control the

functionality of threads as per need. It contains the

following only one method :

abstract void run() : This method is used to write the

code for implementation of thread.

Steps Involved : Here are the below steps that are required to

complete this project.

Step 1: Create a new android project in eclipse with name


5/22



MediaPlayback and package name should be

com.nkm.mediaplayback.

Figure 1: Project name is Media Playback as shown in figure.


6/22



Figure 2 : Package name is com.nkm.mediaplayback

Step 2 : Right click on the res folder and choose> New>Folder

as shown below:


7/22



Figure 3: Choose Folder option as shown in figure.

Step 3 : Give name to the folder raw then click on finish as

shown below:


8/22



Figure 4 : Folder name must be raw as shown in figure.

Step 4 : Put your desired audio file in this folder.


9/22



Figure 5 : Win8.mp3 is media file as shown in figure.

Step 5

Listing 1: Paste the following code inside the main.xml file.


10/22



android:layout_width="wrap_content"

android:layout_height="wrap_content"

android:layout_centerHorizontal="true"

android:layout_marginTop="120px"

android:text=""

android:textSize="42px" />

Step 6

Listing 2: Paste the following code inside the

MediaPlaybackActivity.java file.

package com.nkm.mediaplayback;

import android.app.Activity;

import android.media.MediaPlayer;

import android.os.Bundle;

import android.os.Handler;

import android.view.View;import android.view.View.OnClickListener;

import android.widget.Button;

import android.widget.SeekBar;

import android.widget.TextView;

public class MediaPlaybackActivity extends Activity implem

ents OnClickListener {

SeekBar seek_bar;

Button play_button, pause_button;MediaPlayer player;

TextView text_shown;

Handler seekHandler = new Handler();

/** Called when the activity is first created. */

@Override


12/22



public void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.main);

getInit();

seekUpdation();

}

public void getInit() {

seek_bar = (SeekBar) findViewById(R.id.see

k_bar);

play_button = (Button) findViewById(R.id.p

lay_button);

pause_button = (Button) findViewById(R.id.

pause_button);

text_shown = (TextView) findViewById(R.id.

text_shown);

play_button.setOnClickListener(this);

pause_button.setOnClickListener(this);

player = MediaPlayer.create(this, R.raw.wi

n8);

seek_bar.setMax(player.getDuration());

}

Runnable run = new Runnable() {

@Override

public void run() {

seekUpdation();

}

};

public void seekUpdation() {

seek_bar.setProgress(player.getCurrentPosi

tion());

seekHandler.postDelayed(run, 1000);

}

@Override

public void onClick(View view) {

switch (view.getId()) {

case R.id.play_button:

text_shown.setText("Playing...");

player.start();

break;

case R.id.pause_button:

player.pause();

text_shown.setText("Paused...");

}

}

Step 7 : Run your project and here is the output:

Figure 7 : State of MediaPlayer while pause

Explanantion of above code :

Listing 3: The getInit() method :

public void getInit() {

seek_bar = (SeekBar) findViewById(R.id.see

k_bar);



16/22



play_button = (Button) findViewById(R.id.p

lay_button);

pause_button = (Button) findViewById(R.id.

pause_button);

text_shown = (TextView) findViewById(R.id.

text_shown);

play_button.setOnClickListener(this);

pause_button.setOnClickListener(this);

player = MediaPlayer.create(this, R.raw.wi

n8);


}

This is user defined method which is used to initialize the

GUI controls.

Here the following assignment is used for the creation of

MediaPlayer class object with name player which assignment of

path of the audio file. In this case win8.mp3 is our file which

resides in the raw folder under res folder.

player = MediaPlayer.create(this, R.raw.win8);

The setMax() method of Seekbar class : This method will set

the total duration of seekbar to the total duration of current

audio file.


The run() method : The following code is used to initiate the

Runnable class with an object named as run as shown below.

Listing 4: In run() method seekUpdation() method is called

which means seekUpdation will called again and again till the

playback.

Runnable run = new Runnable() {

@Override

public void run() {

seekUpdation();

}

};

The seekUpdation() method : This method is used to update

the seekbar with delay of 1 second.

public void seekUpdation() {

seek_bar.setProgress(player.getCurrentPosi

tion());

}

Here in this method the following method will set the seekbar

to current position of the playback.

seek_bar.setProgress(player.getCurrentPosition();

And the following method will introduce delay of 1 second in

execution of run() method.


What is Covered ?

In this article we have learned how to play audio files using

MediaPlayer class, how to handle seekbar position with Handler

class and how to control thread execution in android.

Hope you liked the article, see you next time.
